i managed to get into it via safe mode before by holding down the power and home button after i unplugged it in DFU mode, how do i disable the tweeks, i ask becuase before when i was in safe mode cydia and SB settings did not work, i unfortunatly can not swipe to get sbsettings becuase the lockscreen itself will not display the status bar or area.
why did this happen? all i can think of is a tweek did this or becuase i added a few lock screen tweaks at once.
ill try winterboard

to disable the tweaks, i watched a youtube video so lets see, thanks
I'm not certain you were actually IN safe mode, as Cydia works fine under safe mode conditions. I've used it before this way when I had to delete a tweak that had crashed my phone into Emergency Call Only mode. Just tested it again now and it works fine. So I'm a little concerned that you've hosed the Cydia app in some way.
And SBSettings doesn't require a visible status bar to be displayed in normal mode--but no, it doesn't run under Safe Mode.
If you can get in under Safe Mode, disable the passcode through Settings as soon as you get to the Springboard. Then worry about the rest.
*If* these are themes, and if you can get into Winterboard, then yes, you may be able to disable them that way. If they're not themes, WB will have no effect.
iFile also does still work under Safe Mode, so if you can get into that, you may also be able to disable the tweaks by hunting down their main functions--usually they're mostly in a file under /applications. (Or you may be able to do this via SSH from a computer, if you have access that way.) Renaming the whole file for the app by adding -- in front of the current name & rebooting will *usually* disable it long enough to get you back to where you need to be to delete properly from Cydia. But no guarantees, as any time you mess with system files of a running app directly you run the risk of messing things up to the point where restoring is your ONLY option.
As for why, the tweaks you installed are incompatible with something, or with each other. Never add more than one at a time, and read others' reviews on this forum to see if they've had problems before installing anything new.
Oh, and as for the blobs--you can only save them while Apple is still signing them. If you didn't save 4.3.3 weeks ago, you can't save it now. So a 4.3.5 restore will be your only option. Apple does this so people can't roll their firmware backwards.
